Approaching Embarcadero for License for Delphi.

@kotp and I have been discussing the desire to have Travis carry a little more weight for this track. It would be nice if he could be used to trigger automatic checking of submitted exercises (new or updated) via. PR.

I have reached out to the sales department at Embarcadero on (1/30/2017) to see what they would be willing to do for exercism.io seeing how it is a free and open source site.

@kotp's and myself hope Embarcadero see this as an opportunity to give back to the open source community and realize they are gaining some free publicity at the same time.

This is issue is related to #3.
